Good podcasts/vodcasts for long trips?

[Ambrus]

As per the title, I'm embarking on a long (15 hour) train ride tomorrow to visit the family for the holidays and would like to load up my iPod with some interesting podcasts/vodcasts. They don't have to be RPG related, simply engaging and interesting for a geek like me to listen to while staring out a train window. Any suggestions?

Recommended Podcasts

I like listening to "Fear the Boot", "The Sons of Kryos", "All Games Considered". If you like Savage worlds give "The Games the Thing" a try.

I like the podcasts from Scientific American, NPR health/science and environment, National Geographic, and BBC News and Science in Action.

There was also a freebie on iTunes recently where Stephen Colbert read from his new book for about 45 min and then answered questions for about 15. It was some kind of book-related podcast. Hysterical.
